Background technology
At present, the utilization of industrial waste heat is all generally directly be used by heat energy, is that power or electric power export by thermal energy.These method efficiency are lower, generally can only reclaim the waste heat energy regenerating of 10% to 15%.The energy of these methods recovery simultaneously, must use up at once, cannot store, if be just in time in the time period less to energy needs, then reclaim these energy meaningless.
Summary of the invention
For solving the problem, the present invention proposes a kind of technical scheme, industrial waste heat stores by the program, so that when needing most the energy, is used to it.Technical scheme of the present invention is: a kind of Waste Heat Recovery energy storage device, comprises exhaust piping, expander, condenser, heat exchanger, compressor, expansion valve, water pump, low temperature heat storage can, high-temperature heat-storage tank.
Described compressor, condenser, expansion valve, expander connect into a heat absorption loop via pipeline.
Gas working medium is included, in driven compressor current downflow in loop.
Gas working medium in heat absorption loop circulates between compressor, condenser, expansion valve, expander along pipeline, discharges in the heat energy transfer absorbed from exhaust piping to heat exchanger.
Described low temperature heat storage can, water pump, heat exchanger, high-temperature heat-storage tank form the heat accumulation link in a heat accumulation/heat release circulation.
In heat accumulation link, the heat-transfer working medium used is liquid working substance, drives current downflow at water pump.
In heat accumulation link, the liquid working substance in low temperature heat storage can, via water pump, absorbs heat in a heat exchanger, then flow to high-temperature heat-storage tank and stores.
Beneficial effect of the present invention
The Waste Heat Recovery energy storage device that the present invention proposes, is stored after industrial waste heat can being reclaimed, and time energy demand is by the time the highest, then is used to industrial waste heat.It improves the whole efficiency of using energy source, open a new road for industrial waste heat utilizes, while not affecting economic development, will make contributions to energy-saving and emission-reduction, protection of the environment, for the development of green industry civilization provides solid foundation.
